Special Issue Information

Dear Colleagues,

Breast cancer is the most prevalent form of malignancy among women and the leading cause of cancer-related mortality among this demographic, representing a significant global health issue. Despite advances in early detection, molecular profiling, and treatment-improving outcomes, there is a high variability in prognosis and response to treatment in breast cancer patients due to the elevated heterogeneity of this disease. Several factors contribute to this variability, including the biology of the tumor, genetic mutations, tumor microenvironment, the stage at diagnosis, de novo or acquired resistance to treatment, and patient factors. Given this complexity, precision medicine is becoming increasingly important for improving outcomes for breast cancer patients. The identification of novel biomarkers and the understanding of the molecular mechanisms underlying different subtypes of breast cancer are key areas of current research. These efforts are critical for improving early detection, predicting prognosis, and developing more effective, personalized treatment strategies.

This Special Issue of the International Journal of Molecular Sciences, entitled "Molecular Crosstalk in Breast Cancer Progression and Therapies", aims to provide a comprehensive and up-to-date overview of the current state of knowledge concerning breast cancer's pathophysiology and molecular profiling. In addition, it will offer insights into the development of innovative targeted therapeutic approaches, focusing on the promises and potential limitations of these approaches.

Breast cancer (BC) is a neoplasm characterized by high heterogeneity and is influenced by intrinsic molecular subtypes and clinical stage, aspects that remain underexplored in the Colombian population. This study aimed to characterize metabolic alterations associated with subtypes and disease progression in a group of newly diagnosed, treatment-naive Colombian women using an untargeted metabolomics approach. To improve metabolite coverage, samples were analyzed using LC-QTOF-MS and GC-QTOF-MS, along with amino acid profiling. The Luminal B subtype exhibited elevated levels of long-chain acylcarnitines and higher free fatty acid concentrations than the other subtypes. It also presented elevated levels of carbohydrates and essential glycolytic intermediates, suggesting that this subtype may adopt a hybrid metabolic phenotype characterized by increased glycolytic flux as well as enhanced fatty acid catabolism. Tumor, Node, and Metastasis (TNM) staging analysis revealed progressive metabolic reprogramming of BC. In advanced stages, a sustained increase in phosphatidylcholines and a decrease in lysophosphatidylcholines were observed, reflecting lipid alterations associated with key roles in tumor progression. In early stages (I-II), plasma metabolites with high discriminatory power were identified, such as glutamic acid, ribose, and glycerol, which are associated with dysfunctions in energy and carbohydrate metabolism. These results highlight metabolomics as a promising tool for the early diagnosis, clinical follow-up, and molecular characterization of BC. Full article
